Co to 35 Spo (Cor, Veg, Pla, Tun, Jel, Cl) Pr F
Adult: Body laterally flattened with a discoid profile.
Front of body yellow, with mid and rear black. Tail entirely yellow. Llips usually navy blue in Antigua.
Juvenile: Very young specimens, of about 2.5 cm in length, are entirely yellow, except for a blue-edged black spot on the upper side of the body posterior to the midpoint (similar to juvenile Threespot Damselfish qv). With growth, the black spot soon expands to become the large black area covering most of the body and dorsal and anal fins.

Juveniles usually in shallow water, often near or between the vertical plates of fire corals (Millispora spp) and often clean other fish.
When adult, they move to the reef where they feed primarily on sponges. Most common to depths of 25 m.
